i Letters Patent No. 80,531, dated August 4, 1868.

IMPROVEMENT IN MACHINE FOB. GUTTING BAGS.

TO ALL WHOM IT MAY concn'nn.

Be it known that we, ALLAN T. BENNETT and WILLIAM O. ANDERSON, both ofCincinnati, Hamilton county,

Ohio, have invented a new and useful. Carpet-Rag Gutter; and we herebydeclare the following to be a full,

clear, and exact description thereof, reference being had to theaccompanying drawings, making part of this specification.

Our invention relates to a machinefor cutting rags into narrowstrips ofuniform width, for working into what are called rag carpets; andconsists essentially of a gang of hook-formed knives, which projectspirally from a shaft, and are caused to rotate at ahigh velocitythrough corresponding notches in a bench, upon and along which the ragsare drawn slowly forward by a series of feed-\vheels. The said knivesact shearwise with knives or plates 1) on the notched bench.

Figure 1 is a perspective view of our machine, viewed from therear:

Figure 2 shows the bench and the gang of cutters on alarger scale.

The frame A affords journal-bearing to a horizontal shaft, B, armed witha gang of hook-formed. knives, C C C 0 arranged spirally along theshaft, so as to reach the stuff in rapid and regular succession, andthereby cause an equal resistance during the entire rotation of theshaft.

The frame also supports, about on a level with the shaft B, a bench, D,having in its edge nearest to the shaft a series of notches, d til d d,for the passage of the knives.

E E E" E are a series of feed-wheels, arranged intcrinediately betweenthe knives, and journalledin boxes F F, on the extremities ofspring-bearings G G, made fast to the frame, and regulated as to tensionby means of set-screws H H, or otherwise. The spring-bearings, thussecured and adjusted, cause the feed-wheels to press upon the bench,with sufficient force to advance the work, while their yieldingcharacter enables them to act with equal cificien'cy upon rags ofunequal thickness without suspending the action of or clogging themachine.

The knives and the feednvheels aforesaid are driven respectively at ahigh and lowspeed by means of suitable intermediate gearing, partiallyvisible at I and J, fig. 1. v

The machine may be operated either by a crank, K, or by power.

For the purpose of increasing their traction upon the rags, theperipheries of the feed-wheels may be roughened in the manner shown.

The operation is as follows: The-machine being set in operation,.ragsare pushed along the table D until caught by the fecd-whcels, whenthey are dragged forward-by the latter, and cut into shreds by theknives.

If preferred, the notcbed portion of the bench may be made wholly ofsteel or of ease-hardened or chilled iron.

We claim herein as new, and of our invention The combination of the gangof hooked knives G C C C, arranged spirally along the shaft, so as toreach the'material to be acted upon in rap'id and regular succession,the notched bench D, and yielding feed-wheels E E" E E all constructedas described, the knives working intcrmcdiatoly between the feed-wheelsand projections of bench I), for the purpose set forth.

In testimony of which invention, we hereunto set ouch-ands.
